A "Default Option" While Online Grocery Shopping To Enhance Nutrition Within A Food Insecure Population, Jaime Ashley Coffino

Legacy Theses & Dissertations (2009 - 2024)

There is a need for sustainable interventions that improve diet-related health within the food insecure community. We examined if use of a “default” prefilled online grocery shopping cart, compared to nutrition education, would result in the purchase of healthier food items. Fifty participants (M age = 46.4 ± 12.46 years; M body mass index = 28.59 ± 6.48 kg/m2; 74.0% male) were randomized to: (1) read a brochure containing nutrition information (n = 23) or (2) be presented with a “default” prefilled online shopping cart containing groceries that meet nutritional guidelines to which they could freely make changes before completing …

The Effects Of Artemisia Derived Natural Products On Adipogenesis, Steven Abood

FIU Electronic Theses and Dissertations

For the first time in human history, more people worldwide suffer from obesity than are undernourished. Numerous health complications are associated with obesity including cardiovascular disease, Type 2 Diabetes, cancers of reproductive tissues, stroke, depression, anxiety disorders, and Alzheimer’s disease. A deeper understanding of the anti-adipogenic effects and mechanism of action of sesquiterpene lactones may have pharmacological import in the continuing search for therapeutic modalities to ameliorate the effects of this global obesity epidemic.

Dehydroleucodine (DhL), 11,13-dihydro-dehydroleucodine (DH-DhL), and dehydroparashin-B (DhP), sesquiterpene lactones extracted from or derived from compounds extracted from Artemisia douglasiana, were investigated for their anti-adipogenic effects …

A Potential Tool For Clinicians; Evaluating A Computer-Led Dietary Assessment Method In Overweight And Obese Women During Weight Loss, Adrianne Widaman, Nancy Keim, Dustin Burnett, Beverly Miller, Megan Witbracht, Keith Widaman, Kevin Laugero

Faculty Publications

Many Americans are attempting to lose weight with the help of healthcare professionals. Clinicians can improve weight loss results by using technology. Accurate dietary assessment is crucial to effective weight loss. The aim of this study was to validate a computer-led dietary assessment method in overweight/obese women. Known dietary intake was compared to Automated Self-Administered 24-h recall (ASA24) reported intake in women (n = 45), 19–50 years, with body mass index of 27–39.9 kg/m2. Participants received nutrition education and reduced body weight by 4%–10%. Participants completed one unannounced dietary recall and their responses were compared to actual intake. Accuracy of …

Relationship Of Stress, Sleep, Physical Activity, And Food Insecurity On Eating Behaviors And Obesity, Amy Lee Richards

Electronic Theses and Dissertations

There is an urgent need to find effective interventions to prevent and reduce obesity as it is associated with chronic disease and decreased quality of life. Gaining a better understanding of how modifiable variables such as stress, sleep, physical activity, and food insecurity are related to eating behaviors associated with obesity is essential to guide the direction of future interventions and research. Interventions that hold promise need to be tested to determine if they have merit or not. This dissertation presents three papers. Two papers are cross-sectional studies evaluating associations between eating behaviors, obesity, and modifiable variables (stress, sleep, physical …

Measuring The Effects Of High-Fat Diet On Breathing And Oxygen-Sensitivity Of The Carotid Body Type I Cell, Ryan J. Rakoczy

Browse all Theses and Dissertations

The carotid bodies (CB), the primary peripheral chemoreceptors, respond to changes in blood gases with neurotransmitter release, thereby increasing carotid sinus nerve firing frequency and ultimately correcting the pattern of breathing. It has previously been demonstrated that acute application of the adipokine leptin caused perturbations of intracellular calcium and membrane ion movement in isolated CB Type I cells (Pye et al, 2015) and augmented the response of the intact CB to hypoxia (Pye et al, 2016). This study's aim was to examine, in-vivo, if elevated leptin modulated CB function and breathing. Rats were fed high-fat chow or control chow for …
